The length and width of the rectangle are 7.90 inches and 31.6 inches respectively 
It is given that,
Let the length of the rectangle = l 
Let the width of the rectangle = w
The perimeter of the rectangle = 250 inches 
l x w = 250 ....eq 1 
Then,
Length is 4 times as big as width 
4l = w 
We need to find, the length and width of the rectangle 
Putting the value of w in eqn 1 
We get, 




Similarly, we can get,
w = 4l 
w = 4 x 7.90 
w = 31.6
Hence, the length and width of the rectangle are 7.90 inches and 31.6 inches respectively

Answer:
About 40 Minutes, Or something close to that
